High cpu on one of the weblogic managed servers 12.1.3

Hi,

We see cpu usage on a server hosting one of the weblogic 12.1.3 managed servers continuously spikes above 90%. On analyzing found below 4 threads causing the cpu spike along with few others which also have similar stack trace. Any idea what's causing this issue and how it can be fixed?

"[ACTIVE] ExecuteThread: '87' for queue: 'weblogic.kernel.Default (self-tuning)'" daemon prio=10 tid=0x00007fc42809f800 nid=0x126dc waiting for monitor entry [0x00007fc2f130e000]

   java.lang.Thread.State: BLOCKED (on object monitor)

at java.util.Hashtable.get(Hashtable.java:433)

- waiting to lock <0x000000059866b2e0> (a java.util.Hashtable)

Howdy, Stranger!
